Material light flickering on look.

Hello !

The material setup looks like this:

Made the vertex animation with the 3Ds Max script.
The texture is a simple grid, masked out.
Settings:

And just applied on to the mesh.

In a post process volume using FXAA as AA. With no AA a little better, but still pulsing/flickering when I change the players camera.

Thanks for replying!
